New energy vehicle charging gun detection
Test background
With the improvement of people's environmental awareness and concerns about climate change, people have begun to pay attention to reducing carbon emissions and cleaner travel methods. As an emerging clean energy means of transportation, new energy vehicles are gradually recognized and used by people in this context. The popularity of new energy vehicles is inseparable from their low-carbon, environmentally friendly, energy-saving and quiet advantages. Just as gasoline cars need to use a refueling gun to refuel, new energy vehicles use charging guns to charge the car and replenish electricity. Cars are large commodities, and the quality and protection functions of charging guns are very important for new energy vehicles.

Charging gun detection

Charging gun type
First, you have to understand the type of charging gun. According to different charging methods, charging guns can be divided into DC charging guns and AC charging guns.

Comparison between AC charging guns and DC charging guns

AC charging guns are mainly divided into three types, type1, type2, GB/T, which can also be called American standard, European standard and national standard. Tesla has its own standard charging interface, but under pressure, Tesla has also begun to change its standards to make its cars more adaptable to the market depending on market conditions, just like domestic Teslas must be equipped with national standard charging ports.
DC charging guns are generally corresponding to AC charging guns. Each region has its own standards, except for Japan. Some Mitsubishi and Nissan new energy models in Japan will use CHAdeMO DC charging gun interfaces.

Reference Standards
As the scale of the new energy vehicle market continues to expand, the demand for supporting charging gun facilities has also increased rapidly, both in import and export and domestically, and suppliers are overwhelmed. In this case, the quality and safety issues of the charging gun need to meet the relevant standards before they can be circulated on the market. However, different regions have different testing standards for charging guns.

In addition to the differences in working principles, specifications, and usage scenarios, the testing standards for AC charging guns and tributary charging guns are the same. The relevant standards for charging guns are listed here for reference only. The specific standards also need to be determined by the classification of the charging gun and the distribution channels for relevant standard testing.
